TRACK-SIGNAL.

Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed October 10, 1919. Serial No. 329,814.

T 0 all whom it may concern: I

'Be it known that I, ALEXANDER LAWRENCE OURRIE, a subject of the King of Great Britain, and resident of the village of Sorel, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Track-Signals; and I do hereby declare that the following is a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in track signals, of the type adapted to be removably adapted to the track by working gangs or other parties who are temporarily using the track, and the objects of the inven tion are to improve and simplify the construction of the same, to better adapt the various parts to perform the functions required of them, and it consists essentially of the improved construction hereinafter described in detail in the accompanying specification and drawings.

In the drawings:

Figure 1 is a sectional elevation of an embodiment of the invention.

Fig. 2 is a sectional detailtaken through the signal plate showing a method of attachment.

Fig. 3 is a form of attachment. 1

Fig. 4: is a sectional detail having central alternative form.

In the drawings like characters of refer ence indicate corresponding parts in all the figures. 1

Referring to the drawings, A represents the rail, B the tie or sleeper in the same, and C the usual angle or fish plate on the joint of the rail, which angle plate in usual practice leaves a space between the surface of the angle plate and the surface of the rail. D represents the base member of the signal stand. The supporting member is connected to the base member by means of studs 10 and 11 on the base member adapted to enter slots 13 and 14: on the end of the flag sup porting member. represents the flag rod sectional view of an alternative v on top of the flag supporting member connected thereto by means of studs 15 and 16 on the member E adapted to enter slots 17 and 18 in the member F. G represents a flag of any suitable form connected to the mem ber F. According to the present invention.

the base member D is provided with a turned end 19 adapted to enter between the plate G of the rail A; it is also reinforced by a supporting member 20 on the base D having a turned end 21 embracing the outer side of the angle plate. In the alternative form shown in Fig. 3, a set screw 21 is provided in the end 21 adapted to bind the angle plate. A connecting member 23 is provided, centrally connected to the member D having a V-shaped spring having ends 24 and 25 adapted to engage its ends with the angle plate and being adapted to be disengaged from the angle plate by forcing the base member D to flatten the bow shaped member. In the alternative form shown in Fig.

4-, the base member D is composed of two flat strips of sheet metal secured together and having diverging curved ends 26, 27, 28 and 29 which are formed with projections 35 and 36 adapted to enter between the angle plate and the rail at opposite ends, being spring held in spring engagement therewith.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted ALEXANDER LAWRENCE CURRIE.
